@sheila Hi. We no longer support that version of Pencil2D as it had critical issues that made Pencil2D constantly crash and deleting user work files.

As far as I understand we can’t properly support older MAC versions as easily because of how the updated technology used to build Pencil2D is no longer compatible with older versions of macOS; this is courtesy of Apple who are the providers of the key components to the technology framework Pencil2D use, and they don’t like providing their users with much backwards compatibility freedom

That said, I’ll gladly ask developers around to see if there’s any possible way to put forth a version that can be supported in previous macOS versions.

However If you still want to use an older version of Pencil2D, and you understand all of the previous issues as well as the fact that we won’t be able to provide support for most of the older version issues since they were already fixed, here’s a page that contains older versions of Pencil2D: https://bitbucket.org/chchwy/pencil2d/downloads/

@sheila We’re always glad to help. I’m still worried about using an older version, but as I mentioned before I’ll ask to see if it’s possible to output a macOS 10.10 version and I’ll gladly update you through this channel on that regard.

As an additional warning please don’t forget to read the guide I shared previously and If possible please read the known issues sections for previous releases to know about potential issues you or your students might run into. We’ll try to help if it’s within our reach to do so as well if you need anything else related to how the software behaves or operates.
